When I started it and drove off I couldn't hear anything....After letting the car warm up at the gas station getting coffee I had to head back home for something.

I pulled in the driveway and ran inside. I came back out and it was squeaking at idle. I noticed this only once before and it was only slightly quieter before.

I blipped the throttle when it was parked and the squeal went away.

:confused:

I guess I'll mention it to the dealer. Anyone else get this fixed yet?

Someone else posted this in General. It's probably not SRT8 specific but I do remember a couple 8 owners experiencing this.

Ours does a similar thing, I get a constant high pitched whine after driving around with the A/C on. If I blip the throttle, it goes away, but I have noticed the idle drops ~100rpm as well to a normal speed. Did you notice if the idle speed was slightly elevated when yours made the noise?

I should add, not all the time, but very often on ours.

No, it was idling just fine, it just made a little noise is all.

Bad tensioner?

I believe ours is an A/C clutch or A/C compressor issue. It will only do it when the A/C is on and has been on for a while. I'm not sure, but I thought I would ask.

vvv90 what was the weather like? I've seen this happen sometimes when it's really damp out and the tensioner pulley develops condensation. It will stop after everything dries up.

The A/C was definitely not running, and it was beautiful out this morning. The car was in the garage and it wasn't damp. About 80 degrees and sunny. I don't think it's a weather issue.

Sounds like you're right.

I have experienced it with the vehicle parked in the garage as well but not when the weather was nice.

Good luck.

I haven't noticed the problem yet, but when it was really humid back home in southern MS, we used to get quite a few cars doing that back in my pops shop. Hopefully it's just a bad belt, or a tensioner issue, not bad compressor pulleys.

I had this on a non-Chrysler vehicle.

It was related to vertical misalignment of the pullies causing the belt to squeal - difficult to diagnose - but a possibility.

Brother,I got the exact same issue. It doesn't happen all the time,but when it does its like you said,the car has been driven awhile,and I get it back home and there's this slight squeal,until I rev the engine alittle then it goes away.Might be the ever elusive Brampton Canadian gerbil,that has nested in our engine compartments, while the long wait of being built. :silly:

My Dad's SRT8 did this too, in fact I posted a thread here asking about it - - His has 1200 miles on it now; couple days ago I changed the oil for him (yeah i know you don't have to do it that soon but I figure it doesn't hurt after the initial break in of a new engine...) and washed it and I didn't hear that sound even once. Of course I had to test drive it after changing the oil; got it good and warmed up....no noise. I'm gonna call it fixed for now.

slight squeal sound too

Yes, I too hear a very slight squeal sound that is intermittant. Believe it is belt related and possible related to power steering as seems to vary sound pitch if one turns the steering wheel while sitting still.

Have also heard very minor and intermitant tic sound, possibly lifter related, and seen threads here about that too. I will mention all of this to my dealer but not overly concerned. These very slight sounds should be of little or no consequence in my opinion, and they only happen every so often.

Hey, I love the sound of the engine when it turns over, kind of a low growl, and that is every time!

I also heard a loud squeal this morning.

Wonder what it was?
